Program Introduction
Simufact.Welding is a Pre- and Postprocessor-GUI for finite
element welding process analysis. Complex welding process models
with several roboters working at different times can easily be
created. Each of the roboters can work on several welding paths in
a userdefined sequence. Welding paths, directions or sequences can
simply be modified for process variations. As geometrical boundary
conditions the user can choose between bearings, fixations or even
clamping tools with initial forces and stiffnesses. These boundary
conditions are time depended as well as the welding roboters.
As heat input sources there are 2 different models to be
used:
- The 3-D - Goldak heat source with a gaussian volume
distribution, - Gausian surface distribution together with constant
key-hole-volume source.
More than this mentioned heat sources will be implementated in
future.
Simufact.Welding supports the following solvers for the
analysis:
-IFE WeldSim -MSC.Marc
Both of the solvers are finite element solvers connecting
thermal and mechanical solution in one. They have large
capabilities for nonlinear solutions and material behaviour. The
welding analysis can be done with table defined temperature
depending mechanical and thermal material behaviour. Flow stress is
given temperature-, strain- and strain-rate depended. In addition
to that microstructure can be taken into account.
The post processing section of simufact.welding is an easy to
use tool for the result evalutation.
- Distortions can be scaled or compared with the non deformed
structue, - Temperatures, stresses, strains and other results can
be watched as animation during the process. Further: - residual
stresses after cooling, - welding areas, detailled heat
distributions at the welding path, - cutting planes through the
structure
The geometries of the devices are imported as hexahedral or
shell element models in NASTRAN format.

How to work with simufact.welding
Simufact.welding is a WINDOWS application and therefore uses the
same philosophy in its usage.
All present geometric or physical data are stored in an object
box. The welding process itself is described as a tree in the
process box. Simple drag-and-drop functions allow a moving of
entries from the object box to the process tree. In this way they
can be active in several process trees for comparision of process
variations.
Simufact.welding is optimized for simple user input as well as
for best result quality. Depending on the input data, the user can
choose between distortion and residual stress as result up to
microstructure as best result qualitiy.
Although highly nonlinear solutions normally require a lot of
user knowlegde, it is possible to run complex welding processes
with predefined solution settings. Expert users additional have the
possibility to use there own settings, automatically or by menue in
each project model.

Many robots can be defined with a simple menu to control their
temporal sequence. Each of the robots can work along different
welding paths. Times of pause, heating and welding can be
defined.
The heat source direction can be defined global or local. The
graphic model shows that by arrows:
Local direction of the heat source as normal vector

The gaussian heat source for acr welding can easily be defined
as well as a laser source.
